You were his everything. He would make that very clear— always going on missions with you (even though he didn't need to), training with you, and much more. He would sometimes even brag about you to the other hashira, with or without you near him to hear.

That was.. Until you became a demon.

He was so conflicted now. He loved you.. But keeping you alive went against everything he believed in. It would also make him a hypocrite, since he was so against letting Nezuko live. Everyone knew you had become a demon, but everyone save for Genya and a few others didn't know that he had been keeping you at his estate, safe from the others. He was currently meditating near a waterfall while you and Genya wrestled nearby. He knew you weren't a violent demon— as did Genya.. But they would soon need to convince the others as well.
